/* Halden Optometry
   COLOR THEORY
   Harmony: monochromatic plus one accent. A grayscale ladder from paper (#F4F4F1) to ink (#141416) carries the whole page,
   the way an eye chart does: precision, contrast, nothing to distract. One signal orange (#FF4A1C) is the only color and is
   used only where a decision is made (book, result, the two orange frame tiles). Light base, not near-black.
   60% paper       #F4F4F1 / #E8E8E4   backgrounds
   30% ink/gray    #141416 text and dark tiles, #5C5C5A secondary text, #D3D3CF rules
   10% orange      #FF4A1C actions, always with ink text on it
   Contrast (WCAG): ink #141416 on #F4F4F1 16.70 (AAA), on #E8E8E4 14.98 (AAA), paper on ink 16.70 (AAA);
                    gray #5C5C5A on #F4F4F1 6.08 (AA), on #E8E8E4 5.46 (AA); dimmed chart rows #767672 on white 4.7 (AA); ink on orange #FF4A1C 5.47 (AA, buttons);
                    orange on paper 3.05 (large text and graphics only). Photo shoot: grayscale exam portraits. */
